Frequently asked questions

How does Luneo predict my next period?

It averages the length of your last six complete cycles (from one period start to the next) and adds that to your most recent start. Until you have logged two periods it uses the cycle length you set during setup.

How is the fertile window calculated?

Ovulation is estimated 14 days before your next predicted period (you can change this luteal length in Settings). The fertile window covers the five days before and the day after. It is an estimate only and is not a method of contraception.

I forgot to tap Period ended.

An open period stops counting after 12 days. Open the Calendar, tap the last day of your period and switch off Period day for any days that were not period days.

Can I use Luneo only for periods?

Yes. Turn on Settings → Hide fertility info and the fertile window and ovulation disappear from every screen and reminder.

I did not get my reminder.

Open Android Settings → Apps → Luneo → Notifications and make sure they are allowed, and exclude Luneo from battery optimisation. Reminders may arrive a few minutes late to save battery.

How do I move my data to a new phone?

On the old phone use Settings → Export JSON backup (Pro) and save the file. On the new phone use Settings → Import backup. Importing is free.

How do I delete everything?

Open Settings → Delete all data. This removes every log and setting from your phone. Uninstalling the App does the same.

How do I cancel my subscription?

Subscriptions are managed by Google Play, not inside the App. Open the Play Store app, tap your profile picture → Payments & subscriptions → Subscriptions, choose Luneo and tap Cancel subscription. To avoid being charged after the 3-day free trial, cancel at least 24 hours before the trial ends. You keep Pro until the end of the current period. Uninstalling the App does not cancel the subscription.

I bought Pro but the App still shows the free limits.

Make sure the device is signed in to the same Google account you used to buy Pro, then go to Settings → Restore purchases. If a purchase is still "pending" with Google, Pro unlocks automatically once it clears.

How do I get a refund?

Google processes every payment, so refunds go through Google Play: request a refund. We cannot issue refunds ourselves, but email us if you need help with a request.

Does the App upload my data?

No. Luneo has no server and no account. Everything stays on your phone. See the Privacy Policy.

How do I report a bug?

Please email us with what you were doing, what happened, and your phone model and Android version. A screenshot or screen recording helps a lot. We read every report.
